Stealth Rails 🛡️⚡

The Universal Privacy Layer for Solana.

Stealth Rails is a developer-first infrastructure platform that enables one-click, private-by-default transactions on Solana. Powered by Arcium (Confidential Computing), we abstract the complexity of Zero-Knowledge Proofs and Multi-Party Computation into a single, easy-to-use SDK.

Status: 🟢 Live on Devnet | Backend: Real Arcium Network

🚀 The Platform

We are not just a wallet. We are the Stripe for Privacy.

1. The SDK (@stealth-rails/sdk)

Add privacy to any dApp in 3 lines of code.

import { StealthRails } from '@stealth-rails/sdk';

const rails = new StealthRails(connection, wallet);

// 🛡️ Shield & Transfer in one atomic step (MPC)
await rails.sendPrivate({
  to: "Giw...",
  amount: 10
});

2. Stealth Pay (/pay)

A dedicated "Incognito Mode" for payments. Send a link to get paid privately without revealing your main treasury history.

• Try it: Navigate to /pay

3. DeFi Integration (/dex)

See how major protocols (like Jupiter) can integrate Stealth Rails.

• Try it: Navigate to /dex and toggle "Shield Output".

Loading

Core Components:

1. StealthRails Class: The main entry point. It manages the connection to the Arcium Reader Node and the Solana RPC.
2. Arcium Executing Pool: A Program-Derived Address (PDA) on Solana that acts as the "Shielded Pool".
3. Computation Swarm: A network of MPC nodes that listen for encrypted inputs and perform validity proofs off-chain.

📦 Getting Started

Prerequisites

• Node.js 18+
• Solana Wallet (Phantom/Backpack) on Devnet

Installation

# 1. Install Dependencies
cd web
npm install

# 2. Run the Platform
npm run dev

🏆 Use Cases

1. Payroll: DAOs paying contributors without doxxing their salaries.
2. Alpha: Traders entering positions without being copy-traded.
3. Commerce: Merchants accepting crypto without revealing their total revenue.
